    In accordance with the provisions of Article 8 of Federal Power 

Commission License of June 7, 1923 (Project No. 362-Minn., Ford Motor 

Co.), this section is prescribed for the control of the pool level 

created by the Twin City Locks and Dam, Minneapolis, in the interest of

    (a) The pool above the dam shall not be allowed to drop below 

elevation 744.5

(Cairo datum), except after loss or lowering of flashboards and before 

replacement or raising of same, during the navigation season; nor below 

elevation 743.3 during the period when the river is closed to 

navigation. The variation of pool level shall not exceed 0.5 foot per 

day whenever the pool is below elevation 745.5, and in addition, during 

the period when the river is closed to navigation, the maximum rate of 

such variation shall not exceed 0.1 foot per hour; except that during 

the navigation season, increases in pool level at rates greater than 

that specified may be made to eliminate wasting of water during an 

increase in river flow.

    (b) Whenever, due to high flows, the pool above the dam is above 

elevation 746.5, all flashboards on the crest of the dam shall be 

removed or in the lowered position.

    (c) To protect navigation in cases of emergency, such as the 

stranding of a boat or the loss of a pool below the Twin City Dam, etc., 

the licensee shall temporarily discharge water at such rates, subject to 

the limitations of paragraph (a) of this section, as may be directed by 

the U.S. District Engineer in charge of the locality.

    (d) It shall be the duty of the U.S. District Engineer in charge of 

the locality to notify the licensee of the periods during which the 

river shall be considered open to navigation.

    (e) It shall be the further duty of the said District Engineer or 

his authorized agent, by frequent inspections, to determine whether 

paragraphs (a) to (d) of this section are being observed. In case of 

noncompliance he shall so notify the licensee and report the facts to 

the Chief of Engineers.
